LocoMoTlvE ASH-PAN.

SPECIFICATION forming part of Letters Patent No. 377,600, dated February 7, 1888.

Application filed August 6, 1887. Serial No. 246,342. (No model.)

To all whom t may concern,.-

Be it known that I, PERRY J. BROWN, a citizen of the United States, residing at Albuquerque, in the county of Bernalillo and Territoryof New Mexico, have invented certain new and useful Improvements in Locomotive Ash- Pans, of which the following is a description.

My invention relates to an improvement in locomotive ash-pans, the peculiar construction of which will be hereinafter set forth, and its essential features particularly pointed out inY the claims.

The object of my invention is to provide an attachment for locomotive ash-pans whereby the cinders and live sparks are extinguished as they-fall from the grate and are prevented from setting fire to objects along the railroad; and a further object of my invention is to provide means for constantly discharging the said cinders and sparks as they are extinguished,there by dispensing with the ash and clinker pits now in common use, and also relieving the reman of the locomotive from the laborious manual exertion of cleaning out the ash-pan.

In the accompanying drawings, which form part of this specification, Figure lis a vertical longitudinal sectional view ofa locomotive ashpan provided with my improved devices. Fig.

2 is a horizontal sectional view of the same, taken on the line x m of Fig. l. Fig. 3 is a vertical transverse sectional view of the saine, taken on the line y y of Fig. 1. Fig. 4 is a view of a sprocket-wheel as attached to a shaft of the locomotive.

l represents a locomotive tire-box of the ordinary construction, provided at its bottom with a dump-grate, 15, which may be operated by means of a rod that projects beyond one'end of the tire-box, as shown.

2 represents a hopper having inclined downwardly-converging sides and ends. At the upper outer edge of the hopper is a downturned flange, 17, which extends entirely around the hopper. This hopper is secured to the lower side of the irebox,and serves to direct the cinders, sparks, and ashes asthey fall from the grate into the ash-pan. 3, the sides and ends of which are inclined, as shown,and extend above the bottom of the hopper. An air-opening, 4, is left between the sides of the hopper and the sides of the ash-pan, said opening being covered by a sheet of wire-netting, which serves a slight distance above -the bottom thereof, through which the ashes and cinders may be l discharged by the endless conveyer hereinafter described. The said conveyer comprises a pair of shafts, 8, which are arrangedtransversely in the ash-pan, near the ends-thereof, are journaled in the sides of said ash-pan, and have sprocket wheels attached to them, which sprocket-wheels are connected by endlessl chains 5. These chains are connected to each other'by means of transverse dragbars or Scrapers 6.

7 represents a pipe which forms a coil in the bottom of the ash-pan, is provided with a'cock, A, which communicates with the boiler (not shownjabove the water-line or at the steamdome,and is provided also with a cock,B,which communicates with the boiler below the waterline. p y

By opening the cock A steam may be discharged into the ash-pan throughthe open end 19, and by opening the cock B water may be discharged into the ash-pan through said open end and maintained therein at a depth of a few inches, so as to extinguish sparks and cinders as they fall from the re-box. f

One end of one of the shafts 8 projects beyond one side of the ash-pan, and on the same is secured a loose sprocket-wheel, 10, which is.-

adapted to slide on the projecting end of the shaft, and has a clutch, 11, of suitable construction, by means of which it may be secured rigidly to the shaft when the said sprocketwheel is moved inward.' 12 represents a lever by which the sprocket-,wheel 10 may be moved in or out, and thereby engaged with or disengaged from the shaft.

A sprocket-wheel, 14,issecured to one of the shafts of thelocomotive, and is connected to the wheel 10 by an endless sprocket-chain. By this means, when the locomotive is in motion, the conveyer may be kept in constant operation, so as to continually discharge the ex.- tinguished ashes and cinders from the ash-pan IOC as fast as they fall therein, and thus keep the pan clear.

The sprocket-wheel may be made of two semicircular sections bolted together on oppo site sides of the locomotive-shaft, to enable the same to be readily attached to the shaft.

In order to form a bed in the bottom of the ash-pan, I provide a series of bars, 18, which are arranged longitudinally on the bottom of the ash-pan between the longitudinal members of the pipe 7 These bars are slightly greater in thickness than the pipe 7 is in diaineter,and consequently they protect the pipe from injury by friction with the Scrapers or drags of the conveyer.

Having thus described niy invention, I claimm l. The combination ofthe iirebox, the ash- `pan, and the conveyer arranged in the ash-pan, for the purpose set fortli,snbstantially as specified.

2. The combination, in a locomotive, of the iire-box, the ashpan, the endless conveyer arranged in the ash pan, and connections between said Vconveyer and one of the shafts of 25 per 2, depending from the lower side thereof 35 and having the downward-converging sides, the ash-pan arranged below the hopper and having` the inclined sides parallel to the sides of the hopper, and the hangers or brackets connecting the sides of the ash-pan to the re- 4o box, substantially as described.

PERRY J. BROWN.
